Hmmm.... well, are you perhaps just at a good weight for your size? I mean, jeez, you've been working out consistently for quite a while now.... are you sure that's not all muscle??? What is your body fat % ?? Are you maybe just fixated on the number 120? If you're at 20-23% BF or so, it could take a while to get much leaner and you'll just have to be patient.

In any case, I would really like to see what would happen if you rest a week or two. If for nothing else, you can be another guinea pig for us
